Intravenous polymethyl methacrylate after cemented hemiarthroplasty of the hip

Abstract

Current cementing techniques used during hip arthroplasty aim to maximize the bond at the bone-cement interface in an effort to increase the longevity of the prosthesis. To accomplish this, one must generate high intramedullary pressures, which are known to be associated with complications such as cement implantation syndrome. We record a rare complication following cement pressurization of a hip hemiarthroplasty that resulted in intravenous polymethyl methacrylate (PMMA). This complication however, is not associated with a significant morbidity or mortality, but it is important to identify and distinguish from a femoral cortical defect, which can be created during surgery.
